The swordsman clung to the capital for his promise, the swordsman saw through the mortal world and wanted to quit. The bandit wanted to revive Wudang. The son pursued fame and fortune and fought for officialdom. When the four people clashed due to their identities at that time, some saved each other, and some cut off the brotherhood. The four people couldn't help themselves in the general trend of the world and the rivers and lakes, and they lamented bitterly. What will be the final outcome?
